| Description
| - Řada reakčních systémů, které vykazují oscilující nebo jinou komplexní dynamiku v průtočném reaktoru, je založena na oxidaci specifických sloučenin síry, jako například siřičitanu či thiosíranu, různými oxidačními činidly. V naší předchozí práci jsme začali zkoumat mechanismy oxidace těchto sloučenin peroxidem vodíku. Dříve používané metody pro studium reakční kinetiky, které byly založeny především na měření pH, byly nyní rozšířeny měřeními časových závislostí koncentrací hlavních složek systémů technikou infračervené spektrometrie spočívající na zeslabeném úplném vnitřním odrazu (FT-IR/ATR). Tato měření poskytla cenné a v jisté míře detailní informace o časovém vývoji thiosíranu, siřičitanu, tetrathionanu a trithionanu. Navržený reakční mechanismus vede k matematickému modelu, který může být porovnán s měřenými daty takovým způsobem, který nebyl dostupný v předchozích studiích. Prezentujeme předběžné výpočetní výsledky, které vykazují velmi dobrou shodu s výsledky experimentálními získanými pro vsád (cs)
- A number of reaction systems that provide oscillatory and other complex dynamics in a flow-through reactor are based on oxidation of specific compounds of sulfur, such as sulfite and thiosulfate, by various oxidation agents. In our previous work we started examining mechanisms of oxidation of these compounds by hydrogen peroxide. Techniques used so far for the investigation of reaction kinetics, which involved mainly the use of a pH-meter, were extended by measurements of the time evolution of concentrations of major components with Attenuated Total Internal Reflectance Infrared Spectroscopy (FT-IR/ATR). These measurements provide valuable and rather detailed information on the time evolution of thiosulfate, sulfite, sulfate, tetrathionate, and trithionate. The underlying reaction mechanism leads to a mathematical model, which can be compared with measurements in many ways not feasible in earlier studies. We present preliminary results showing a very good agreement with experimentally observed batch-o
